Laravel new在我的本地环境中不起作用

Question

我正在尝试创建一个新的laravel应用程序，但是当我使用命令"laravel new“时，我得到了一个错误：

laravel new
Crafting application...
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for phpunit/php-token-stream 2.0.0 -> satisfiable by phpunit/php-token-stream[2.0.0].
    - phpunit/php-token-stream 2.0.0 requires php ^7.0 -> your PHP version (5.6.30) does not satisfy that requirement.   Problem 2
    - phpunit/php-token-stream 2.0.0 requires php ^7.0 -> your PHP version (5.6.30) does not satisfy that requirement.
    - phpunit/php-code-coverage 4.0.8 requires phpunit/php-token-stream ^1.4.2 || ^2.0 -> satisfiable by phpunit/php-token-stream[2.0.0].
    - Installation request for phpunit/php-code-coverage 4.0.8 -> satisfiable by phpunit/php-code-coverage[4.0.8].

Application ready! Build something amazing.

我使用的是Windows10，安装了php 5.6.30。

我已经尝试过更新composer本身和laravel的安装程序(通过composer global需要"laravel/ installer ")，但它仍然不起作用。

我最后一次用这台电脑是在三个星期前，当时它还能用。

编辑:我不能更改我的PHP版本，因为它是我在服务器上使用的版本。

Answer 1

看起来您正在尝试下载laravel的最新版本。虽然是5.4，但由于某些原因，它正在下载仅与PHP7兼容的laravel版本尝试使用composer create-project --prefer-dist laravel/laravel blog "5.4.*"安装laravel 5.4

Answer 2

这只是phpunit版本。将版本更改为更小，如下所示：

"phpunit/phpunit": "~5.7"

至

"phpunit/phpunit": "~5.0"
